Static Stress Changes and Triggering Imposed by Wenchuan Earthquake on Lushan M7 Earthquake

Some faults rupture the surface followed by coseismic dislocation, which causes space stress changes and transmits or imposes static stress on or to neighboring faults.The static stress triggering leads to the adjacent fault ruptured in advance, which means a Coulomb stress increase and triggers a new earthquake event. In recent two decades, some studies on stress triggering became important field of seismotectonics. The occurrence of both Wenchuan M8.0 earthquake and Japan M9.0 eathquake have arisen interest of many researchers, and obtained much new result and understanding.
